I found those injectors, and just wondered as I know a few members are running them. Do they fit just like the stock injectors do? They look the same, just a different color. Do the electrical connections fit with no issues also?

According to the wiki the numbers line up. http://miataturbo.wikidot.com/fuel-injectors
IanFerrell(spelling lol? Sorry Ian) is using rx8 injectors, they are a complete stock drop in, no modifications. I'd pm him if you have questions.

You need these: http://cgi.ebay.com/ebaymotors/4-EV1...Q5fCarQ5fParts
They will idle better than the injectors you posted above, will be more consistent and provide a lot more headroom. Completely PNP.

I must've looked at the link I originally posted too fast. I thought it was $74.99 for the set of 4 injectors, not by the piece. ****.
I figure, my 460's have been bad luck for me. Time to go with a different style, and I'm thinking something more like the 195500-4450.

Not sure why you want a picture, it's in your previous post.

I was just making sure there's not some special injector to head seal that increases the over length of the injector. I didn't explain that original picture very well. I was trying to show the how the difference in injector length is about the same as the thickness of the spacer. So when I put the RX8 injectors in I just had to leave the spacer out and now they fit fine.

they only look shorter by about 2mm.

the amount the pintle sticks out doesn't matter. What matters is how short they are once they are fit into the head/manifold.
it looks like the edge the insulator sits on is about 2mm off.
